M.2 NVMe to OCuLink Adapter for LattePanda Dev Board (PCIe 4.0 x4, up to 64Gbps)

The M.2 NVMe to OCuLink Adapter converts an M.2 NVMe M Key slot into a high-speed OCuLink interface for external PCIe device expansion. Delivering PCIe 4.0 x4 speeds up to 64Gbps, it is ideal for makers and developers looking to connect external GPUs or high-bandwidth peripherals to LattePanda dev boards and compact single-board systems.

High-speed PCIe 4.0 x4 bandwidth

Based on the PCIe 4.0 x4 specification, this adapter provides direct interface conversion with peak transmission bandwidth up to 64Gbps. It enables high-throughput data transfer between your system M.2 slot and OCuLink-based expansion hardware.

Multiple M.2 form factor support

Designed for versatile mechanical layouts, the adapter board accommodates 2230, 2242, 2260, and 2280 M.2 sizes. This ensures broad physical compatibility with varied mounting configurations.

Durable industrial-grade PCB build

The double-layer black PCB features a 10u-inch immersion gold process engineered for high-frequency transmission, low resistance, and oxidation protection. The gold-plated edge fingers comply with IPC Level 1 international standards.

Robust thermal and flame resistance

With an operating temperature range of -40°C to 80°C and a UL 94V-0 flame retardant rating, the board maintains reliable performance across demanding operating environments.

LattePanda and eGPU integration

This interface adapter is suited for external GPU expansion on LattePanda series microcomputers and other development platforms requiring high-bandwidth PCIe connections.
